At least one person was missing, presumed dead as snow turned to rain and deluged the Pacific north-west on Friday, causing flooding, landslides and avalanche danger in the mountains.
A 72-year-old man never returned after leaving his residence to move his car to higher ground on Friday in Cosmopolis, Washington, according to Grays Harbor Undersheriff Brad Johansson. The man’s residence was on a road that was flooded and authorities fear his vehicle was swept into floodwaters down a steep bank next to his driveway, Johansson said.
Snow and rain forced the closure of parts of two major highways – Interstate 90 and Interstate 5 – with flooding also swamping roads throughout western Washington and Oregon.
In south-western Washington’s Lewis county, a 20-mile stretch of Interstate 5 was closed in both directions south of Chehalis because of flooding from the Chehalis River. The major route across Washington’s Cascade mountains – I-90 over Snoqualmie Pass – closed on Thursday due to avalanche danger, heavy snow and low visibility. Stevens Pass on US 2, White Pass on US 12 and Blewett Pass on US 97 also closed.
Officials said all four passes that connect western Washington with eastern Washington would probably remain closed until Sunday.
The Washington governor, Jay Inslee, issued an emergency proclamation because of severe winter storms going back to 17 December.

Dozens of watches and warnings were in effect in Washington and Oregon, including a flood warning for the northern Oregon coast following huge rainfall.
